[0025] As attached Figure 1 To be continued Figure 3 As shown:

[0026] This utility model provides a DC power supply cabinet, including a cabinet body 1. The cabinet body 1 has an installation chamber 2 inside. The installation chamber 2 has several electrical racks 3 arranged from top to bottom inside. The installation rack 4 is installed in the installation chamber 2 at a position parallel to each electrical rack 3. The installation rack 4 has a first sliding groove 5 on the side close to the electrical rack 3. An auxiliary cooling fan 6 is slidably installed in the first sliding groove 5, and the output end of the auxiliary cooling fan 6 is directly facing the electrical rack 3 at the parallel position. A first drive assembly is installed in the first sliding groove 5. A main cooling fan 7 is installed on one side of the installation chamber 2. Ventilation openings 8 are provided on both sides of the cabinet body 1. Through the heat dissipation of the main cooling fan 7, the auxiliary cooling fan 6 and the ventilation openings 8, the heat accumulation inside the cabinet body 1 is reduced, thereby extending the service life of the DC power supply cabinet.

[0027] The first drive assembly includes a first screw 9, which is rotatably installed in the first slide groove 5. The first screw 9 passes through the left and right sides of the auxiliary cooling fan 6 and is threadedly connected to the auxiliary cooling fan 6. By rotating the first screw 9, the auxiliary cooling fan 6 moves under the limiting action of the first slide groove 5, thereby achieving heat dissipation for electrical components at different locations.

[0028] The first motor 10 is installed on one side of the first slide groove 5, and the output end of the first motor 10 is connected to the first screw 9 through a coupling. The first motor 10 drives the first screw 9 to rotate, thereby driving the first slider to move.

[0029] This utility model provides a sealing fire extinguishing mechanism, including the DC column cabinet in the above embodiment, and also including a mounting base 11 and a monitor 12. The mounting base 11 is installed on one side of the cabinet 1. A second slide groove 13 is provided through one side of the mounting base 11. A second slider 14 is slidably installed in the second slide groove 13, and the two ends of the second slider 14 extend to the two sides of the cabinet 1 respectively. A pair of baffles 15 are symmetrically installed at the two ends of the second slider 14. The baffles 15 are in close contact with the cabinet 1, and the size of the baffles 15 is larger than the size of the vent 8. A second drive assembly is installed in the second slide groove 13. The monitor 12 is installed at the top of the mounting chamber 2. By raising and lowering the baffles 15, the vent 8 is blocked when a fire occurs, thereby reducing the amount of air entering the cabinet 1 and suppressing the fire.

[0030] Among them, a pair of baffles 15 are provided with sealing gaskets 16 at the edges on opposite sides, which facilitates the sealing effect of the baffles 15 on the ventilation openings 8.

[0031] The second drive assembly includes a second screw 17, which passes through the upper and lower ends of the second slider 14 and is threadedly connected to the second slider 14. When the second screw 17 rotates, the second slider 14 moves under the limiting action of the second slide groove 13, which in turn drives a pair of baffles 15 to move, thereby enabling the baffles 15 to block the vent 8.

[0032] The top of the mounting base 11 is equipped with a second motor 18. The output end of the second motor 18 is connected to the second screw 17 via a coupling. The second motor 18 is also electrically connected to the monitor 12. The monitor 12 can be an FC72 series smoke detector, an HFP207 series fire alarm, etc. It can monitor the smoke temperature and other conditions inside the cabinet 1, and transmit a signal to the second motor 18 when a fire is detected. The second motor 18 is powered by an external power supply to prevent circuit failure caused by a fire.

[0033] One of the pair of baffles 15 has a vacuum pump 19 installed on one side, and an exhaust pipe 20 is installed on one side of the vacuum pump 19. The other end of the exhaust pipe 20 passes through the baffle 15. The vacuum pump 19 is electrically connected to the monitor 12 to facilitate further exhaust of air from the cabinet 1 and reduce the oxygen content inside the cabinet 1.

[0034] The working principle of this embodiment is as follows: When the sealing fire extinguishing mechanism and its DC cabinet are in use, the main cooling fan 7 and the auxiliary cooling fan 6 are turned on, which, together with the ventilation opening 8, increases the air circulation speed inside the cabinet 1, reduces heat accumulation, and when the temperature of some electrical components is high, the operator can turn on the first motor 10 at the corresponding position. The first motor 10 drives the first screw 9 to rotate. Under the limiting action of the first slide 5, the auxiliary cooling fan 6 moves to the vicinity of the electrical component for targeted heat dissipation and cooling. When a fire occurs inside the cabinet 1, the monitor 12 transmits a signal to the second motor 18 and the vacuum pump 19. The second motor 18 drives the second screw 17 to rotate. Under the limiting action of the second slide 13, the second slider 14 moves and drives a pair of baffles 15 to move, so that the baffles 15 can block the ventilation opening 8. The vacuum pump 19 can exhaust the air inside the cabinet 1, reduce the oxygen content inside the cabinet 1, thereby suppressing the fire and reducing the spread of the fire.
